Trade only? Yes, you go first
I'm a casual f2p player who's been around religiously since before Naxx. I jump between wild and standard, get all the adventures with gold, and get dozens of packs from every expansion (all with gold).
This month, I hit legend for the first time. It felt like a big deal! I finally got the card back and prestige I've looked up to other players for having. But after the pride and celebration wore off, I thought "What now?" I'm currently content with being #2680 in Wild Legend. Do I just keep playing and vie for a higher spot for pride? Do I turn my sights on Standard? Other than bragging rights, what do I do now? Daily quests and battlegrounds? I had never felt the Hearthstone fatigue until now. I always had something to strive for, but now I guess I just twiddle thumbs until next season and try again then.
What do others do when they start to feel that end-of-the-month-hearthstone-ennui?
